水下机器人数字光纤传输系统的研究与设计

针对某探坝遥控式水下机器人(ROV,remotely operated vehicles)在水下作业时需要与岸基之间完成导航、动力控制和探测信息收集等大量的数据交换的问题,文中设计了一种在1根光纤中传输所有信息的数字光纤传输系统,整个系统的设计核心是基于一片FPGA芯片的高速串行收发器.在高速串行收发器的设计过程中,分别介绍了发送器与接收器的整体结构和功能,利用QuartusII和Modelsim等仿真软件分别对高速串行收发器的各功能模块进行仿真验证,并将该模块应用于整个传输系统中,完成了系统数据传输的要求.该FPGA芯片在系统中的应用不但可以降低系统板级的体积和复杂度,而且实验证明,系统的抗干扰性得到了很大的提高.

The design of fibre-optic digital transmission system based on underwater vehicles

A high-speed serial transceiver was presented based on one FPGA chip which is used to transmit a great deal of data between the console and underwater robot on a fiber, accomplishing navigation, power control and collection of detection information, and so on. As to the design of this transceiver, the authors introduced the whole structure and function of the transceiver, then all of the modules were simulated by the simulation software of Quartus II and Modelsim. Finally this receiver was applied to the en...
